IMPROVEMENT IN CLOTHES-WRINGERS.

Specification forming part of Letters Patent No. 153,182, dated July'21, 1874; application filed June 21, 1873.

To all whom it may concern Be it known that I, BENJAMIN SMITH, of estMilton, Saratoga county and State of New York, have invented certainImprovements in Olothes-lvringers, of which the following, taken inconnection with the accompanying drawings, is a full, clear, and exactdescription.

This invention relates to that class of clotheswringers in which therollers are governed by flat leaf-springs adj ustably secured at one endto the wringer-frame, and hearing at the other end upon the axis of therollers. Heretofore, in this class of wringers, the axis of thefeedroller, as well as that of the presser-roller, has been held inplace by means of the plate-sprin g. This construction has proveddefective, in that it permits the feed-roller to be wrenched from itsposition when thick or heavy materials are passing between the rollers.To obviate this is the object of my invention; and it consists inarranging the bearings of the feed-roller in the frame-pieces, andapplying the spring only to the axis of the pressing-roller.

In the drawings, Figure 1 is a perspective view, and Fig. 2 a plan, ofmy improved wringer. Y

a a are the base pieces, upon which the several parts are assembled, andin rear or underneath which are attached the ordinary clamps forsecuring the wringer to the tub. Upon the top of the base-pieces aresecured the leaf-springs ff. These springs are of metal, and are madeflat and straight, and of sufficient length and strength, one end ofeach being hooked to carry the projecting shaft of the pressing-rollerc, and the other end of each secured to the base-pieces, in which isjournaled the axis of the feeding-roller (1. Upon the end of thesebase-pieces I secure the guides g g, in such mannerthat they cover theends of the rollers. An apron, Z), generally of wood, unites the twobase-pieces a a firmly together, and is made of sufficient width tosecure the passage of clothes from between the rollers to the tub.

It will be observed that by the use of these flat straight sprin gs f fconstructed as shown, and secured to the base-pieces, as described, thepressing-roller 6 will recede from the roller 6 so nearly in a verticaldirection without any guide or slot for its axis, that the relativepositions of the rollers and frame will remain substantially unchanged,thereby obviating the difficulty arising from the oscillation of therollers.

The tension of the springs is easily regulated by the set-screw, but thesprings being made broad and straight little or no change is required inthe tension, and the liability to set is obviated.

It will also be observed that by journaling the axis of the roller 01 inthe base-pieces a a, the displacement of said roller (when in use) withrespect to its bearings, is prevented.

I do not claim as my invention a spring made of metal or other material,with a curved end to hold the pressing-roller, nor do I claim theguards; but I Having fully described my invention, what I claim as new,and desire to secure by Letters Patent, is

In a clotheswringer, having base-pieces a a, apron b, and guards g g,the presser-roller e, governed by flat leaf-springs f f, adjustabysecured to the frame, in combination with the feed-roller (Z, journaledin said base-pieces, as and for the purposes specified.
